The Rogue One: A Dark Matter-Dominated Dwarf in the Trail of Dark Matter-Deficient Galaxies
Daniel Vaz, Arsen Levitskiy, Duncan Forbes +6
We present the first measurement of the stellar velocity dispersion of LEDA 4014647, a compact dwarf galaxy spatially aligned with the NGC 1052 trail, a linear chain of dark matter…
The Stellar Populations of Two Quiescent Low Surface Brightness Dwarf Galaxies in Low Density Environments
Duncan A. Forbes, Hannah S. Christie, Arsen Levitskiy +3
Dwarf galaxies located in low density environments that have quiescent stellar populations are extremely rare and the mechanism for quenching their stars is highly uncertain. Here…
Diffuse Dwarf Galaxies in Galaxy Clusters: I. Stellar Populations and Radial Gradients
Arsen Levitskiy, Duncan A. Forbes, Jonah S. Gannon +5
We use Keck/KCWI spectroscopy to study one ultra-diffuse galaxy (UDG) and five Nearly-UDGs (NUDGEs) in the Perseus cluster, together with an additional UDG in the Coma cluster. As…
Connection Between Dwarf Galaxies and Globular Clusters: Insights from the Perseus Cluster Using Subaru Imaging and Keck Spectroscopy
Yimeng Tang, Aaron J. Romanowsky, Song Huang +11
We present a systematic study of 189 dwarf galaxies and their globular cluster (GC) systems in the Perseus cluster, based on deep Subaru Hyper Suprime-Cam imaging and Keck spectros…
Tidal Disruption of Super Star Clusters as the origin of Bluish Light at the inner region of the Perseus Cluster Central Galaxy
Arsen Levitskiy, Youichi Ohyama, Jeremy Lim
Relatively blue light extends beyond a spiral disk from a radius of ~5 kpc out to ~14 kpc from the center of NGC 1275. Analyses of its spectrum and broadband colors reveal a popula…
A Comprehensive Look at PUDG-R21: Stellar Population and Kinematics of a Globular Cluster-Rich Ultra-Diffuse Galaxy in the Perseus Cluster
Arsen Levitskiy, Duncan A. Forbes, Jonah S. Gannon +5
We present the analysis of the stellar populations and kinematics of the globular cluster (GC) rich ultra-diffuse galaxy, PUDG-R21, using spectroscopic observations obtained with t…
Radial velocities and stellar populations for a sample of MATLAS survey dwarfs
Kate Southon, Jonah S. Gannon, Duncan A. Forbes +4
Spectroscopic observations are essential for confirming associations, measuring kinematics, and determining stellar populations in dwarf galaxies. Here, we present Keck Cosmic Web…
Constraining the z 1 Initial Mass Function with {\it HST} and {\it JWST} Lensed Stars in MACS J0416.1-2403
Sung Kei Li, Jose M. Diego, Ashish K. Meena +19
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date, the IMF is constrained only to local galaxies. Indiv…
Star Formation, Nebulae, and Active Galactic Nuclei in CLASH Brightest Cluster Galaxies. I. Dependence on Core Entropy of Intracluster Medium
Arsen Levitskiy, Jeremy Lim, Youichi Ohyama +2
We set the stage for reassessing how star formation, emission-line nebulae, and active galactic nuclei (AGNs) in brightest cluster galaxies (BCGs) depend on the thermodynamics of t…
